German Herring Salad

I am feeling a bit tired today, but still I refuse to have a nap, although I didn't have too much sleep the last few days. For next week things should run normal and I will get enough sleep. So, no need to interfere.
I rather use the time to write a recipe down for you. Some say, you should eat more fish. Then that is what we are going to do. There are one or two items in my pantry, I could ask myself "why did I  buy them?". There has to be a reason.
Now there is this jar of beetroot. Why did I get it? No idea. However, I know what I can do with it. One thing is German Herring Salad. Then I am going for some fish at the same time. That sounds good.

Let's do it then ...
